' Application nieu october 10,1883. (No man.)

Tall whom it muy concern,.- n Be it known that I, Max SEMBRITZKI, `of Schlglmiihl, near Vienna, Austria-Hungary, have inventeda 'new and useful Improved Paper-Making Apparatus, of' which the following isa full, olea-r, and exactdescription. This invention consists in apparatus for nieehanically carrying out the process of making fibertel-made paper, the systenreoniprising,

irst, a paper-maker mold ot special construcsecond, the application of pneumatic exhaustion to the undersurface ot' the mold to facilitate the draining of the paper-pulp and the coaching of the sheet; third, a distribution of the pulp, whereby a given quantity may be poured uponand spread verthemald; hurt-h,

nthe combination ot the arrangements constituting a new system of apparatus for mechanically making hand-made paper. g In order-that the invention mapv be more readily understood, I have illustrated an ex- `ample thereof in the accompanying drawings,

Without, however, limiting myself to the forni or details of the parts therein represented.

Figure 1 is a side elevation of the whole system; Fig. 2, a longitudinal sect-ion; Fig. 3, a pla-n; Fig. 4, a vertical section, showing the arrangement and mounting of the mold and the pneumatic exhaust applied thereto. 'i's a diagram representing the various niotions given to the mold.

In all these figures the same letters indicate the same parts. r

A is the mold, iitted within a easing, a.

- having double u'alls, between which the pulp overflowing from the mold A is received ,to be returned to the vat. The mold is free to receive a slight vertical motion within this Casing through the agency of 'jointed push-rods b, riding upon rails c. The mold A, with its double easing e, rests upon a carriage'l, moving upon Ways for the purpose of transporting themold to and fro bet-Ween the pulp-distrib` uting and the couching apparatus. During its forward movement the myold passes betiveena pair of vibrating arms, d, pivoted at their one end,and connected at their other end to a crank or other mechanical motion, .whereby a lateral shaking motion is imparted to the mold and its casing. The mold thus receives, first, aunifornl alternate rectilinear motion of trans- Fig. l

lation; second, a vertical'motion at each traverse of the mold; third, a' horizontal lateral shaking motion.

- The exhaust beneath the mold for draining I the pulp and facilitating the couching ofthe sheet is effected at the desired moment by the unclosing of the mouth of a tube, e, pendent froin'the carriage B,and sliding upon a partlyhorizontal and partly-inclined slide, f, or bv a self-acting cock.

The pulp-distributer consists of a chest, D, having open tubes a, fixed in holes inthe bottoni and rising Within the chest, said tubes be-` ing arranged in rows iu regular order. A plunger, 2', is fitted to Work up andA down in thewchest, the plunger having vertical hole 'in it corresponding to the tubes 11., but of sufficiently greater diameter to allow the pulp displaced bythe descent of the plunger toiise through said holes and overflow down the tubes h, the mechanism being so arranged that this shall occur when the mold arrives beneath the chest.

The operation of the apparatus is'as follows! The tank C is supplied with purified pulp by any suitable regulated means, whence it flows through tubes g to the distributing-chest D.

peint ofthe mold covered with pulp,the travel of the mold being from m to y and back again from y to In its forward motion the mold passing between the pair of arms d, in order to spread the pulp uniformly upon the mold, discharge the excess-into the space between the double walls a, and cause the fibers composing the pulp to become felted together. .Up to this point of the operation the mouth of the tube e remains closed by resting uponthe horizontal part of the slide f; but by the continued advance of the .carriage the mouth of the tube passing over the downwardly-inclined part of the slide becomes gradually-inclosed, allowing the drainings from the mold which have collected in the tube to run cti', tliereb5r producgo receives a transverse vibratory 1not1onwh1le v -v ing an Aenhaustive effect beneath the` pulp, Y Whichkmaybe regulated bysuitably arranging vthe inclination of the slide, or by a cock placed on fpipe l; W'henthe mold 'has arrived at` y, f

the pulp is almost completely drained, andbecomes entirely so by the Vvibratory upward' l motion from y to y', which it receives by the l jointed rods b riding up the inclined ends of j the rails e (or by any other suitable means) on Vated position, and on arriving at Z the mold touches the couch-*roll E, whereby the sheet is taken oli' and couehed upon the endless -felt or blanket, which travels at the saine velocityas 'the mold-carriage. passes beneath one or more press-rolls before The sheet being eouched it arrives at the drying apparatus, which may be combined with the above; or the sheet may v I bers.
